Vintage 80’s Sheer Scarf / Shawl

This is from my mothers closet, new, never worn - no tags. Drapes and feels like silk, But likely a nylon or a poly-rayon blend,maybe (?) Ive spotted a couple “defects” in the fabric that I noted in the photos. 1) small white dot 2) a fine line that appears in the weave. Both are not detectable when wearing but I must disclose. Measures approx 19”x 62”.
